TUNING-BUTTON.

SPECIFICATION forming part of Letters Patent N o. 675,742, dated June 4, 1901.

Application filed March 25, 1901. Serial No. 52,686. (No model.)

To all whom, it may concern:

Be it known that I, ARTHUR J. LANG, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Tuning- Button, of whichv the following is a full, clear, and exact description.

My invention relates to that class of tuningbuttons which are used at the neck-section of stringed musical instruments.

The purpose of the invention is to provide such a tuning-button with a light yet durable metal head and to firmly secure such a head on the stern or shank of the button in an eX- peditious, effective, and simple manner.

The invention consists in ythe novel construction and combination of the several parts, as will'be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of one section of the head. Fig. 2 is a perspective view of the second or opposing section of the head. Fig. 3`is a transverse section through the stem v or shank of the button and its head, showing the two sections of the head connected. Fig; 4 is a longitudinal section through the head and a side elevation of the shank or stem4 of the button, and Fig. 5is an enlarged cross-section through the stem or shank and through the completed and shaped head of the button.

The device consists, primarily, of three partstwo cap-plates A and B, which are adapted to be brought together, and a stem or shank O, an end of which is to occupy a position between the cap-plates. The stem or shank is provided between its ends with an annular groove 11, and in the drawings the stem or shank C-is shown as provided with the usual exterior thread employed in connection with screw-buttons.

The section A, which is shown` in detail in Fig. 1, consists ofa circular cap-plate 12 and a marginal iiauge 13, in which liange a recess 14 is produced. Both of the sections A and B are constructed from light or sheet metal, such as brass. The section B of the head comprises likewise a cap-platel and a marginal flange 16; but this flange 16 is oset from the cap-plate, forming an annular shoulder 17 where the cap-plate and its flange connect, and the fiange 16 of the section B is provided with a slot or recess 18, which extends usually to the cap-plate. The flange 16 of the section B is of less circumference than that of the flange 13 of the section A, since the flange 16 of the section B is to telescope within the iiange of the opposing section A when the two parts are brought together.

Before the two parts or sections A and B are brought together the plain end of the stem or shank C is made to enter the section A at the recess 14, and the side walls of this recess fit into the annular groove 11 in the stem or shank, as is illustrated in Fig. 4. The opposing section B of the head is now placed within the section A, theslot or recess 18 in the section B receiving the shank, permite ting the two cap-plates of the two sections to lie in close engagementwith opposite sides of the shank or stem, as is clearly shown in Figs. 3, 4, and 5.' Next the free edge of the flange 13 of the head-section A isbent in ward to fit the shouldered portion 17 of the opposing section B, as is shown also in Figs. 3, 4, and 5, filling the space which was made to produce the shoulder, and when the iange of the section A is thus bent or crimped upon the outer section B the outer face of the capplate 15 of the section B will be substantially iiush with the outer face of the bent or crimped portion of the flange of the opposing section. The two sections of the head now firmly engage with the stem, and the completed head is then rolled so as to produce the coneaved faces 19 (shown in Fig. 5) in both cap-plates at opposite sides of the shank. When the head is so rolled, its outer edges are of less transverse thickness than its central portion, while the central portion of the head clings securely to the stern or shank. This curvature is imparted to the head in order to :render said head more conveniently gripped betweenthe thumb and fingers, and is also present in the usual heads made of wood, celluloid, and the like.

The main purpose of this invention is to provide not only an inexpensive head and onel IOO check, split, or break when'subjected tosudden/blows;v

Having thus described my invention, ,I claim as new and desire to secure by Letters Patent- 1. In a tuning-button, a head'therefor, consisting of opposing cap-plates each provided with a marginal liange, the ilange of one capplate being offset to extend beyond the capplate,'the said Iiange being adapted to telfv escope Within the opposing section, the ange of each section of the head being provided with recesses therein adapted to register, the

` free edge of the flange ofthe outer section of the head being bent inward to engage with the shoulder formed by the offset of the iiange of the smaller or opposingsection of the head.

2. In a tuning-button, a stern or shank and a headconstructed of metal in two sections,

each section comprising a cap-plate and a 4 ange, the ange of one section being adapted to enter the iange ofthe opposing section,` the flanges of both sections having openings to receive the stem or shank, the flange of the smaller section being oset, extending out-beyond the cap-plate of said section,
